To all whom it may concern:

Be it known that I, Gustavo ESPINOSA on DB8 MoN'rnnos, a citizen ofMexico residing at El Paso, in the county of lill Paso and State ofTexas, have invented certain new and useful Improvements in Blast Devices for Shoe-Polishing Machines, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to a blast device for a shoe polishing machineand has for its principal object the production of a device which is soconstructed as to apply polish to a shoe and then to dry the same andatterward polish the shoe, thus dispensing with the necessity of theemployment of the ordinary brushes and other paraphernalia now in usefor the purpose.

Another object of this invention is the production-of a l. last devicefor a shoe polishing machine wherein the base has a ban dle formedthereon so as to permit the same to be easily lifted,while the motorhousing carried upon this base permits the entire device to: be easilylifted and moved to a position desired so as to facilitate the polishingof shoes.

Another object of this invention is the production of a blast device fora shoe pol-- ishing machine wherein the funnel is de mountably carriedupon the motor housing so as to direct the air currents from the motorhousing to the shoe u on which the polish' is being applied, this unnelbeing adapted to be removed when so desired for applying a brush to themotor shaft, whereby" the brush may either apply the polish to a shoe orburnish the shoe afterward as desired.

With these and other objects in view this invention consists of certainnovel combinations, constructions, and arrangements of parts as will behereinafter fully described and claimed.

In the accompanying drawings:

Figure 1 is a side e evation of the blast device for a shoe polishingmachine.

Referring to the accompanying drawings.

by numerals it will be seen that 1 designates a base plate which has thehandle 2 formed upon its rear end and extending for a considerabledistance thereabove. This handle 2 has a sleeve 3 formed upon one sidethereof and through the handle 2 and sleeve 3 there extends a bore 4 forthe reception of the conductor wires 5 wt ich extend therethrough. Themotor 6 is mounted upon the base 1, as shown in Figs. 2 and 3 and isheld in a fixed set position by means of the screws 7 which pass throughthe base of the motor 6 into engagement with the base plate 1. The wires5 are connected to the motor 6 so that a suitable supply of electricitymay be supplied to the motor for running the same. It is, of course,obvious the v; suitable form of a motor may be ..mployed either of adirect or alternating type and also of any desired size.

The motor housing 8 is substantially circular in cross-section at itscentral portion, although it tapers toward its end, and is mounted uponthe base plate 1. The straight side walls 9 extend from the centralportions of the housing 8, depending for a considerable distancetherebelow and having the horizontally extending base flanges 10 formedthereon, which flanges rest upon fhe base plate 1. The retaining screws11 portions of the motor housing pass through the base flanges 10 intoengagement with the base plate 1 and thus fixedly secure the motorhousing 8, in a set osition upon the base plalie'l. 'It should he notedthat the motor housing and the walls 9 thereof are formed of anysuitable material, preferably metal, although they may be of anysuitable substance so as to minimize their weight when applied to thebase plate 1.. Since the motor housing 8 is circular at its cen ralportion sufficient space is provided for the accommodation of the motor6, as shown in Fig. 2. The rear end of the motor housing 8 is providedwith a number of intake openings 12 so that when the motor is runningair may be sucked into thednterior of the motor housing by m ans ofthe'fan 13 mounted upon ihti motor shaft 14. This fan 13 may be retainedin a set position by means of the set screw 15 as shown in Figs. 2 and5. As the ends of the motor housing converge the air being drawn in oneend will be condensed by the opposite reduced end and discharged withconsiderable force therefrom. lhis last-mentioncd end of the motorhousing 8 is provided with an annular collar 16 to receive the funnel.The funnel 17 has a collar 18 which is adapted to demountably fit uponthe collar 16 of the motor housing 8. The collar 16 of the motor housing8 is provided with pins 19 which are-adapted to fit within the bayonetslots 20 of the collar 18 of the funnel 17. Thus, it will be seen thatthe funnel may be applied to the collar of the motor housing 8 so as topermit the pins 19 to be directed into the slots il after which act.onthe funnel may be turned to one side, thus permitting the pins to restwithin the inner portions of the slots 20 and thus hold the funnel frombeing accilvnlally displaced when in use. This funnel l7 tapers towardits outer end, as shown clearly in Fig. 5. although the outer end isflared, as shown at 21 comprising a blunt bearing surface, provided theend of the funnel con'ies into engagement with the shoe which is 11 ngpolished.

The brush used for applying the polish to the shoe comprises a shaft 22having an enlarged inner end 2? in which there is forn'ied a socket 2-1.square-d n cross-section, as shown in Fig. 11, so as to lit upon. thesquare end 25 of the motor shaft 14. The set screw 26 is carricd by theenlarged. inner end 23 of the brush shaft 22 so that after the squareend B5 of the motor shaft 14 has been inserted in the square socket 24,the set screw may be turned so 15 to bind upon the motor shaft it andthus hold the brush shaft 22 in a fixed engagement therewith, whereby asthe motor shaft rotates the rotary motion will be imparted to the brushshaft 22. This brush shaft 22 is provided with a reduced This sorkct 24is outer end 27 upon which are positioned the washers 28 and 29.'lhefahric sheets 30 which constitute the brush are positioned upon thereduced end 27 of the brush shaft 22, being interposed between thewashers 28 and 29. The retaining nut 31 is threaded upon the outer end.of the reduced end 27, thereby holding the. washers .28 and .29 and thefabric sheets 30 in fixed engagement with the outer reduced end 27 ofthe brush shaft 22. Thus, it will be seen that polish may he applied toa shoe by means of the fabric brush 30 for after the polish has beenapplied to the brush and the same is being rotated by the motor thebrush may be positioncd upon the shoe and the polish will be evenly andthoroughly distributed upon the surface of the shoe. As soon as thepolish has been applied to the shoe the brush shaft 22 may be detachedfrom the motor shaft 14, after which action the funnel may be placedupon the collar 16, as shown in Fig. 5. The motor may thenbe againstarted so that the air being discharged from the funnel may quickly drvthe polish and thus dispense with the necessity of using the customaryarticles now employed for accom lishing this function.

After the polisli has become dry the shoe may be easi y burnished bymeans of the soft brush 32. The brush shaft 22 is provided with anenlarged inner end 23' in which there is formed a square socket 24' soas to receive the square end of the motor shaft 14. The set screw 26will detachably retain the brush shaft 22 in ei'igagomcnt therewith.Upon the forward end of the brush shaft 22 there is carried a coilspring 33 by means oF the rivet 34 which secures the coil spring to theforward end of the brush shaft 22'. The opposite end of the ill spring33 is secured by means of the pin 35 carried by the cup 36 upon whichthe soft brush 32 is mounted. The yiuldahle rubber boll 37 is mountedupon the forward, end of the brush shaft. 22' so as to overhang thespring as well as the brush 32. Thus, it will be seen that if this'brushis used for applying polish to a hoe the yieldable boll 37 will preventthe polish from being thrown cit'hcr upon the operator or the pa tron.Furthel'morc, it will be seen that since the brush 32 is yieldablymounted sun-c the spring supports the same in burnishing a shoe it willyield slightly as the shoe is being rubbed and thus prevent the shoefrom being rubbed too vigorously, which action would remove the polishwhich has been prior-1y applied thereto.

From t e foregoing description it will be see rthat' a very elhcientshoe polishing machiaehas been provided, which is so conspuctbd' as tovery quickly polish a pair of s ions," owing to the fact thatthepolishing means now commonly employed for accomplishing this purpose aredispensed with and owing to the rapidity with which the.

fan housing havin tapering ends will constitute a director or the airwhich is being blown upon the shoe for dryinthe same. lhus, it will beseen a shoe p0 ishing ma chine has been provided which will cientlyaccomplish all purposes as set forth, and which is comparatively simplein opera: tion, cheap in construction, andformed of a minimum number ofparts for the purposes specified.
